Version Information:

Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.225

why am I having this problem and how do I get rid of it?

Solution

Try performing a full solution build. If that doesn't work, click Build -> Clean Solution. If the error persists, delete everything in the C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\parktms folder and repeat.

thanks it worked but can you tell me what went wrong to avoid future mishaps

[Chris Gessler]

The compiler was unable to copy one of the output files to the temp folder. File might have been in-use at time. Hard to say without seeing your build or system logs.

im using mygeneration in my project now its saying Error 1 The type or namespace name 'SqlClientEntity' could not be found (are you missing a using directive or an assembly reference?) E:\Projects\parkingticket\Projects Application\ParkTMS\App_Code\Generated_vw_Tickets.cs 22 38 E‌​:\...\ParkTMS\ while i have added doodads reference

@ChrisGessler God I hope you're still active. Any suggestions about a WinForms WebSite and not a project. I do still have the Build Project and Build Website buttons (VS17, so no "Clearn") But the site is run off of IIS and is copied and not deployed ?

The only thing "Clean Solution" does is delete the output files from the bin folder. You can do that step manually.
